Abstract

We report the synthesis of porous CoMoO₄ nanorods and their applications in lithium oxygen (Li-O₂) and lithium ion (Li-ion) batteries. The unique porous structures of CoMoO₄ nanorods can promote the permeation of electrolyte and benefit the transport of lithium ion. When employed as the cathode catalyst for a Li-O₂ battery, CoMoO₄ nanorods deliver an improved discharge capacity (4680 mA h g^-1), lower charge potential and better cycle stability (41 cycles at 500 mA h g^-1 capacity limit) compared with the bare carbon. When employed as an anode in Li-ion batteries, CoMoO₄ nanorods can retain a capacity of 603 mA h g^-1 after 300 cycles (400 mA g^-1) and exhibit excellent rate capability.
